The film explores the concept of electricity, demonstrating how it can be generated through simple experiments such as rubbing different materials together. It explains the basics of electric ...

A galvanometer is converted into a voltmeter by connecting a high resistance in series with it. Give an example of a substance whose resistance decreases as temperature increases.

Noninvasion, low-power consumption, and wide-range measurement of sensor nodes in wireless sensor networks remain a large challenge for smart grid and Internet of things (IoT). A noninvasive passive ...

Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

A galvanometer is basically a very sensitive ammeter that moves — it can also be used as a very precise electro-mechanical actuator, for say, moving a tiny mirror.
